6.3.3 Other Key Function Calls
Remember to call
after all the Wi-Fi parameters have been defined. The
sock_init()
Wi-Fi interface will be up automatically as long as you configured Dynamic C at compile
time with one of the
macros. Otherwise the Wi-Fi interface is neither up nor
TCPCONFIG
down, and must be brought up explicitly by calling either
or
ifup(IF_WIFI0)
. You must bring the interface down when you configure
ifconfig(IF_WIFI0,…)
Dynamic C at run time before modifying any parameters that require the interface to be
down (see Section 6.3.2) by calling
or
.
ifdown(IF_WIFI0)
ifconfig(IF_WIFI0,…)
Then bring the interface back up.
Finally, no radio transmission occurs until you call
.
tcp_tick(NULL)
Instead of executing the above sequence based on
, you could use
sock_init()
sock_
as a debugging tool to transmit packets (ARP, DHCP, association,
init_or_exit(1)
and authentication) while bringing up the interface and to get the IP address.
